Wälzlager für eine geradlinige Bewegung

摘要

In a roller bearing (1) for the straight-line movement of a supporting component (2) along a guide rail (6), the quantity of relubrication is to be minimised regardless of the installation position of the roller bearing (1). This is achieved by the invention in that a separate lubricant line (13) is inserted in a channel (10) of a head (8) for the lubricant supply which takes the form of a single-lipped seal (16) in a region in which lubricant exit points are desired.
